Dumpster diving in Missouri is not outright illegal, but its legality depends on property rights, local ordinances, and how and where you access the dumpster.
What Missouri Law Says
No Statewide Ban: Missouri does not have a specific state law prohibiting dumpster diving.
Private Property: Entering private property without permission to access a dumpster is considered trespassing, which is illegal and can result in a Class B misdemeanor. This includes dumpsters located behind fences, inside locked gates, or marked with “No Trespassing” signs.
Public Property: Dumpster diving is generally legal if the dumpster is on public property or if trash is left at the curb for collection, as established by the 1988 Supreme Court case California v. Greenwood. Once trash is placed in a public area, it is considered abandoned and there is no reasonable expectation of privacy.
Municipal Ordinances: Some cities and towns in Missouri may have their own rules restricting or regulating dumpster diving, so always check local ordinances before diving.
Signage and Locks: If a dumpster is locked, fenced, or has signage prohibiting entry, accessing it is illegal and can lead to arrest or citation for trespassing.
Littering and Disorderly Conduct: Even if dumpster diving is allowed, leaving a mess or creating a disturbance can result in fines for littering or disorderly conduct.
Key Points to Remember
Legal on public property: You can legally dumpster dive if the trash is in a public space and not otherwise restricted by local law.
Illegal on private property: Accessing dumpsters on private property without permission is trespassing and subject to criminal penalties.
Local rules matter: Always check city or county ordinances, as some municipalities in Missouri may have stricter regulations or outright bans.
Respect signage and boundaries: Ignore “No Trespassing” signs, locks, or fences at your own legal risk.
Be responsible: Clean up after yourself to avoid fines for littering.
